To (ZZZ whom it may concern.-

Be it known that I, ANDREW WIGGINS McCULLoUcu-r, a citizen of the United States, residing at Homer City, in the county of Indiana and. State of Pennsylvania, have in vented certain new and useful Improvements in Calendars for Watchcases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in calendars for watchcases, and comprises a simple and eflicient device of this nature whereby a perpetual calendar is roduced which may be set easily and quickly adjusted at the beginning of each month.

My invention comprises various details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accomp anying drawings, in which- Figure 1 is a perspective View of a watch with the cover open, showing the application of my invention. Fig. 2 is a detail view of the disk bearing the numerals and removed from the cover of the case. Fig. 3 is a second disk having the abbreviations of the days of the week, and Fig. 4 is a sectional viewshowing the manner in which the disk is held to the cover.

Reference now being had to the details of the drawings by letter, A designates a watchcase having a hinged cover A, and B designates a disk adapted to fit inside of the cover and having upon its face adjacent to its periphery at equal intervals the abbreviations for the days of the week. Said disk B frictionally engages the inner periphery of the inturned flange of the cover, whereby said disk may be held in place and allowed to turn axially therein.

0 designates a disk, a detail of which is seen in Fig. 2, having a scalloped or cutaway portion C formed at regular intervals in the circumference thereof and adapted to disclose the various abbreviations of the days of the week in the manner shown in Fig. 1 of the drawings and also heldfrictionally Within the cover in the same manner as disk B is held, the two disks being held with their adjacent faces in contact with each other and each without pivotal connections with each other or with any other part. The face of the disk C is divided by radial lines into segments bearing various numerals indicating the days of the month upon which a certain week day occurs during a particular month in radial columns.

In the drawings are illustrated seven radial divisions upon the disk C, and upon each division appear the names of one or more of the months of the year. The divisions containing the names of two or more months have corresponding numerals arranged in radial lines, which numerals indicate the number of times a certain day in the week will occur during the month.

In adjusting the improved calendar the disk shown in Fig. 1 is turned so that the letter S will be disclosed near the scallop in alinement with the stem, and the calendar will be set for the current month, and reading to the right may be seen the days of the week occurring underneath each scallop to the right, and when one circuit has been made of the disk by dropping to a second numeral in the radial series underneath in alinement with the stem and the abbreviation for Sunday will be found the day of the month of the new week, and by placing the numerals to the right in the same manner in the corresdponding series may be seen each successive From the foregoing it will be noted that a simple and eflicient calendar convenient for carrying in watches is provided whereby the various days of the week and months may be readily observed upon the mere setting of the calendar at the commencement of each month.

What I claim is 1. A calendar for watches comprising, in combination with the cover of a watch having its edge inturned, forming a flange, disks held frictionally by said flange and adapted to rotate axially without pivotal connections with each other, one of said disks being divided by radial lines into spaces corresponding to the number of days in a week and adapted to disclose numerals indicating the days of the month, the other disk designed to disclose at intervals, abbreviations for the days of the week, as set forth.

2. A calendar for watches comprising, in combination with the cover of a watch having its edge inturned forming a flange, disks he d frictionally by said flange and adapted to rotate axially without pivotal connection with each other, one of said disks being divided by radial lines into spaces corresponding in number to the days of a week, the outer marginal edge of the disk divided by radial lines being recessed, forming means whereby the disk may be rotated the other disk adapt-
